Got the Stahlwille 8-piece double offset ring wrenches, 6-22 mm, skipping 21mm. Smoother finish than the Hazet, but good in the hand. Great price at Amazon.de (EUR 62.50).
Recieved Hazet 600SPC/10 set, 8-19 mm, skipping 9 and 11mm.
Probably mentioned here before, but check out the markings on the 13mm wrench, "150 - HAZET - 1868 - 2018":
